KAMM 1540 University Park
- Thread starter AM1000
- Start date
I was in DFW this past weekend and heard nothing on 1540. Also no sign of life on 1220, 1460, and 1700. I did find 890 back on the air, had been missing during an early August visit.
KAMM has been granted an extension of its STA to operate with 100 watts from what is essentially a TIS/HAR type whip antenna located on the western edge of the University Park city limits.
The attachments to the latest STA filing are interesting reading, as the owner discusses his research into finding a permanent transmitter site. It appears the favorite is the former KVIL 1150 location near Stemmons and LBJ, though a number of other possibilities are listed, including diplexing with KKDA.

hows that possible?
KEXL skywave cpould be an issue.. theres no way 100 watts into a fairly inefficient antenna is making it 45 to 50 miles pretty decently at night
well i heard the legal id at the top of the hour and they were playing what sounded like indie rock. and it was at night during skywave propagation. is that good enough for you? or am i going to have to record it and put it on youtube? plus i never heard kxel here

KXEL’s night signal has never been an issue in DFW. If you look at their directional pattern there is a null towards DFW.
Back when 1540 in DFW was a Fort Worth station (KCUL/KBUY) it had no listenable night signal into Dallas County. KXEL could occasionally be heard, but never at any decent strength.
I’m not doubting the report of KAMM near Sherman. Perhaps that whip antenna has quite a bit of vertical incidence, which would result in short distance skywave.
I heard a 50 watt AFRTS station at Ramey, Puerto Rico in Cleveland, Ohio, once. It was 100% readable... about 2,100 miles. It used a tower that was about 1/20th wavelength!
"I’m not doubting the report of KAMM near Sherman. Perhaps that whip antenna has quite a bit of vertical incidence, which would result in short distance skywave."
that's kind of what i was thinking.
After the famous STephen lockwood tuned up the array about 5-6 years ago, it did well into Wyoming
The 1540 1kw night signal from Kennedale was good over Fort Worth. However I do recall that as you drove east of Loop 820 along 121/183 the signal would quickly disappear.
The Kennedale 50kw day signal did okay over Dallas County. Not particularly strong, but listenable reception.
The Kennedale site was closed sometime in the mid 1980s…that might have been when the COL changed to University Park. Would have to dig through old FCC records to be more precise. The 1540 signal has come from a couple of different sites since then.After the famous STephen lockwood tuned up the array about 5-6 years ago, it did well into Wyoming
I'm thinking the COL changed to University Park sometime in the mid-to-late 90's. I remember it being licensed to Ft. Worth last time I lived in DFW, which was 1996. Only heard it in passing a few times, though, as the Spanish-language religion format it had at the time wasn't targeted at me in any way, shape, or form!
Thread bump: KAMM has filed for a further extension of its current STA. In attachments to the filing it is stated that they were unable to obtain use of the old KVIL 1150 transmitter location near LBJ and Stemmons, and are now looking at a site near Spur 348 and Luna Road, where they supposedly have plans already drawn up for a permanent array, pending various permits. We shall see.

on the day of June 10, 2024… KAMM 1540 is looping a PSA about “Don’t Mess With Texas” the station is looping the PSA throughout the day, do you guys think if this is a technical problem with the station, or if it’s just no one monitoring the station
Sure there is. I heard 50 watt AFRTS radio from Ramey AFB in Puerto Rico on 780 in Ohio. It's antenna was a 50 foot tower.
With the suppression of skywaves on some nights all over the U.S., this is not as unlikely as it seems.
It may just be broadcasting to hold the license.
In that context, it is sort of like being "slightly pregnant".
Thread bump to note that NTRG has filed yet another STA extension for KAMM. Appears they may now be looking at a possible diplex.
From the latest filing:
“NTRG has been diligently searching for a new site to relocate the directional antenna system required to relicense this facility. At the time that the previous extension of this was granted, NTRG was in the process of negotiating a sub lease of part of the Elm Fork Gun Range. NTRG is still in the process of dealing with the City of Dallas and other parties involved in the permitting process at this time. Unfortunately this process has taken longer than expected. This may be due to the fact in a change of leadership at the City of Dallas. NTRG is making contact with the new city manager in hopes this process can move forward. NTRG is also considering a diplex site with another facility and is investigating an agreement and costs to construct.”
